SPRING-WHEEL.

T0 .all whom if may concer/11,.'

Be it known that I, Fnninmcn NV. J. Gonnscn, subject of the Emperor of Germany, residing at Cleveland, in the county oit' `(.hiyahoga and State of Ohio, have in* vented `a new and useful Spring-lVheel, of which the following is a specification.

The present invention relates to improvements in spring wheels, the primary object of the invention being the pro-vision of a novel arrangement. of hub and spoke member, the connection between which is composed of a plurality of springs, an auxiliary means being provided for adjusting the tension ol said springs to regulate the re siliency of the springs.

A further object of the present invention is the provision of a spring wheel, the main hub member of which constitutes an annular receptacle for the spoke carrying member, said spoke carrying member being permitted a limited movement therewithin, both members being provided with spring carrying portions to provide a resilient connection between the spoke carrying member and the hub member.

A still further object of the invention is the provision of a novel adjusting means to regulate the resiliency of the springs.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-ligure 1 is a dianietrical sectional view through the hub and spoke carrying members of the spring wheel. Fig. 2 is a plan View taken 'from the side thereoit' carrying the spring adjusting disk. Fig. 3 is an inner plan view ot' the removable disk of the hub member. Fig. 4t is an enlarged detail View of the spring adjusting disk. Fig. 5 is an enlarged sectional view taken on the line of Fig. 8. Fig. 6 is a diagrammatic view illustrating the action of the spring adjusting lugs and one spring.

Referring to the drawings, the numeral 1 designates the main disk of the hub member which is provided with the concentrically disposed axle engaging sleeve Q, whose outer end is threaded as at 3 and Specification of Letters Patent.

provided with a .key way 3. A disk fl is slidably mounted upon the sleeve 2 and is made similarly to the disk l, said disks 1 and 4l. providing an annular receptacle for the reception of the spoke carrying member composed of the disk 5, concentric sleeve G, and annular disk 7, said annular disk 7 being mounted upon and exterior of the end of the sleeve (i, as clearly shown in Fig. 1. The bolts S are disposed through the respective disks 5 and 7 and clamp the said disks together to retain the inner ends of the spokes 9 relatively to the spoke carrying member. lhc sleeve (3 is disposed con centrically or' the sleeve Q o'l the member 1 and provides the concentric chamber l0 so that `the spoke carrying member is permitted a gyratory movement between the disks 1 and 4 and relatively to the sleeve 2.

In order to limit the sliding movement and at the same time resiliently support the spoke carrying member with relation to the disks 1 and el, the disks 1 and l are provided with the circular recesses 11 and 11 respectively, the recesses 11 upon the disk 1 being disposed diametrically opposite to each other, while the recesses 11 formed in the disk et are diametri :ally opposite to each other but disposed at 90O angle with relation to the recesses 11 of the disk 1.

Upon the outer face of the respective disks 5 and 7 and disposed to aline with the respective recesses 11-11 ol the disks l and 4t, are the circular recesses 12 and 12', respectively, which coact with the opposed recesses l1 and l1 oli the disks l and 4, to provide a receptacle for the lap or open ring springs 13, there being one spring to cach receptacle formed by the recesses. The ends (iic of the spring are so disposed as to slide one past the other, and as the spring 1.3 is wide enough to project within the recess oit both members 1 and 5 and 4 and 7 respectively, a proper resilient support 'for the spoke carrying member with relation to the hub member is provided, and therefore the sliding movement oit the spoke carrying member relatively to the hub member is limited by the springs 13.

In order to regulate the tension ot' the respective springs 13 and thus limit lo a ccrtain extent `the movement oil. the spoke carrying member, under varying load crmditions, the disk 14|: is provided, said disk 1st being provided with the central aperture 15 which is disposed to fit upon and over the threaded end 3 of the sleeve 2 eXteriorly of the member 4, as clearly shown in Figs. 1 and 2. A key 16 is insertible within the key way 3 and engages the slot 15 of the member 14, and thus locks the member 14 relatively to the sleeve 2, but permits of the necessary movement of the member 4, which as shown is provided with a plurality of threaded apertures 17 for the reception of the adjustl mg screws 18, said screws being insertible through either one of the respective apertures 19 of the disk 14 to thus lock the disk or member 4 fiXedly with relation to the spring adjusting disk 14.

In order that the contact surfaces of the springs relative to the walls of the recesses 11-11 and 12-12 may be reduced, four lugs 2O are carried by the respective disks 1 and 4, while four lugs 20 are carried by the respective disks 5 and 7, the position of the disks 4 with relation to t-he spoke carrying disk causing the relative position of the recesses 11-11 and 12-12 and the lugs 2O and 20 to change to permit of the contraction or expansion of the springs 13 and consequently the decrease or increase of the resiliency thereof.

In order to readily adjust the springs, the disk 14 is provided with the teeth 21 at diametrically opposite sides thereof in its periphery and said teeth are disposed in the position adjacent to the respective recesses 22 of the hub member 4, so that the actuating lever 23 may have its pivoting stud 24 disposed within one of the recesses 22 with the tooth 25 disposed to engage one of the teeth 21. By this means the disk 14 may be locked with relation to the disk 4, until the respective bolts 18 are removed. After such removal, the bearing downwardly upon the lever 23 will cause the disk 4 to be rotated relatively to the disk 14 or until one of the apertures 17 is placed in line with one of the apertures 19 of the disk 4, at which time 'the respective bolts 18 are inserted to engage and lock the members relatively together.
